{"Authorization": "Basic Base64_ENCODED_APPKEY_APIKEY"}

You can obtain the username and password details from the MoEngage Dashboard.

Navigate to Settings > Account > APIs.
Copy the following details:
- Username: Under Workspace ID (earlier App ID), click the copy icon to copy the username.
- Password: In the API keys section, click the copy icon in the Campaign report/Business events/Custom templates/Catalog API tile to copy the API key.
